论文摘要
我们报告了一种新技术,用于实现二阶相关性($ g^2(τ)$)测量在低重复速率脉冲激发(1 kHz)下,并进行了定时抖动以恢复横向$ g^2(τ)$ curves并确定$ g^2(0)$。我们使用CDSE纳米线(NW)激光来演示经过抖动的$ g^2(τ)$测量,其中$ g^2(0)$进化显示了激光发射过渡过程。令人兴奋的脉冲分为参考和激发通道,当令人兴奋的脉冲具有明显的正时抖动和低重复率时,可以使抖动校准。使用参考信号校准和重新排列单光子信号后,可以完全恢复侧面$ g^2(τ)$曲线,并从我们的方法中证明了$ g^2(0)$进化。
We report a new technique for the realization of second-order correlation ($g^2(τ)$) measurement under low-repetition-rate pulsed excitation (1 kHz), with timing jitter calibrated to restore lateral $g^2(τ)$ curves and determine $g^2(0)$. We use CdSe nanowire (NW) laser to demonstrate the jitter-calibrated $g^2(τ)$ measurement, where $g^2(0)$ evolution shows the laser emission transition process. The exciting pulses are split into reference and excitation channels, which enables the jitter calibration when the exciting pulses have significant timing jitter and low repetition rate. After using the reference signals to calibrate and rearrange the single-photon signals, lateral $g^2(τ)$ curves can be entirely restored, and $g^2(0)$ evolution is demonstrated from our method.
